//容器中嵌套容器

void test01()
{
	vector> v;

	//先创建小容器
	vector v1;
	vector v2;
	vector v3;
	vector v4;
	vector v5;

	for (int i = 0; i < 5; i++)
	{
		v1.push_back(i + 1);
		v2.push_back(i + 2);
		v3.push_back(i + 3);
		v4.push_back(i + 4);
		v5.push_back(i + 5);
	}

	//将小容器中数据插入到大的容器中
	
	v.push_back(v1);
	v.push_back(v2);
	v.push_back(v3);
	v.push_back(v4);
	v.push_back(v5);

	//通过大容器，把所有数据都遍历一遍
	for ( vector >::iterator it = v.begin(); it != v.end(); it++)
	{
		//(*it) -- 容器   vector
